Discreet flexible pixel elements connected in series comprise flexible pixel strings that are conformably applied to irregular shapes and surfaces thereby to produce free-form electronic displays and signage. Means for serial connection of discreet flexible pixel elements enable efficient power, data and control signal distribution. Image data conversion means translates conventional graphical image data into visual image data and control signals to drive discreet flexible pixel elements. The discreet flexible pixel element, serial connection means, and signal distribution means of the present invention enable efficient, economical production of large scale, free-form electronic displays, signs and lighting effects.
